通过阴极射线示波图和数学分析，解释了超再生接收器中出现的主要现象。结果证实了一个较早的理论，即在单独猝灭的探测器中，接收到的信号只是使探测器在每个猝灭周期中以最大输出振荡较长时间，而不增加振荡的最大幅度。结果还表明，在自猝灭探测器中，信号只产生猝灭频率的增加，而不增加振荡所达到的最大幅度。讨论了超再生接收机的灵敏度、选择性和特性噪声。
By means of cathode-ray oscillograms and mathematical analyses the principal phenomena occurring in superregenerative receivers are explained. The results verify an earlier theory that in the separately quenched detector the received signal merely causes the detector to oscillate at maximum output for a longer period during each quench cycle, without increasing the maximum amplitude of the oscillations. It is also shown that in the self-quenched detector the signal merely produces an increase in the quench frequency, without increasing the maximum amplitude reached by the oscillations. The sensitivity, selectivity, and characteristic noise of superregenerative receivers are discussed.
